The warmest heated vest for men yet! Mobile Warming started with premium RDS sourced natural duck down and added a high capacity 7.4volt Powersheer XL micro heating system to produce a jacket with superior warmth and comfort, stylish enough to wear every day, with the bonus of performance heat when it's needed the most during extreme winter conditions. 5 heat zones deliver hours of warmth and are easily adjusted between 4 temperature settings from the integrated touch control button or cell phone using the innovative Bluetooth technology and the MW Connect App. WaterpellTM water resistant outer shell keeps you dry all day, and if it's late in the day and night, the Powersheer XL battery has a built-in flashlight with cell phone charging, in case your phone needs a burst of power. You'll want to use the Crest Jacket with a removable hood for casual day trips, or longer excursions in the great outdoors.
